Why Choose the Mersen F086186 Protistor® High-Speed Fuse?
The Mersen F086186, also identified by catalogue number FD20GC100V50T, is a high-speed cylindrical fuse specifically developed for the protection of semiconductor devices and critical DC circuits. Part of the Mersen Protistor® 20 × 127 mm gR range, it delivers fast, full-range overcurrent protection for sensitive industrial power electronic equipment.
This fuse features a gRC operating characteristic engineered to limit the damaging thermal and electrical energy passed to semiconductor components during overload and short-circuit conditions. Its rapid current-limiting performance helps reduce equipment damage, improve system reliability and minimise costly downtime.
With a rated current of 50 A and an IEC voltage rating of 1000 V DC, the F086186 is suitable for auxiliary circuits, control equipment, measuring devices and monitoring systems. Its integrated striker provides a clear indication when the fuse has operated and can support remote status monitoring when used with compatible fuse holders or microswitch accessories.
